Hey, it's her party and she'll go pantless if she wants to — we just hope she didn't pass on panties!

Christina Aguilera was spotted leaving her birthday party in El Lay on Tuesday night, and it seemed like she had a grand old time!

The just-turned-32-year-old looked all partied out in a familiar tattered Mickey Mouse t-shirt and fishnet stockings worn with knee-high boots and a long sparkly duster that kept us from seeing too much.

As anyone with a birthday in December do, Xtina accessorized with a Santa hat.

Hey, at least she wore some form of clothes instead of prancing around in her birthday suit, right?
